Be it known that I, GEORGE lV. Fluxes citizen of the United i ltates,resicliug t Pittsfield, in the county of Berkshire State ofMassachusetts, have invented ceita-in new and useful Improvements inElectrotherepeutic Apparatus, of which the following is a specification.

The invention relates to electrotherepeutic apparatus-for the treatmentofcertsin (lisee-ses, "being designed especially to increase thecirculation of the blood by electrically messaging the ai'ectecl parts;and it consists in regu liiting the frequency of operation and intensityof the electrical impulses, from a battery of other suitable electricalsupply circuit, by means of e rheostet or voltagereguletoi',saidimpulses being provided; by interrupting ail electric circuit, anddischarging the same into the rheostet oi" volt age regulator ancl theninto an elec procoiitects electrical connection Withpositive P o tivecurrents.

In the drawings-Figure l is cliagz'e-rm metic View of myelectrical-messa e ratus; 2 is a central, lent tion of theinduotiomooil, v and frequency-regulator; Fig. 's s 1 View of the e sewith lid open, showing: arrangement various parts of the eppemtus, andFig, 4: is an edge ViSW of the electrocle.

Referring to the several views, the numeral 1 indicates e suitable caseor box proviclecl With a hinged licl or top 2. case is preferablydivided into tli ee ccinjoertmerits, one of which contains a suitablesource of electrical supply, such a battery 3, another theinduction-coil 4 the batteryswitch 5, and the frequency-regulator 3 andrheostet 7, anti the remaining one containing the cable reel 8, and theelectrocle 9 when not in use.

]j;,The imluction coil l is supportetl in a yoke 10 of closed magneticcircuit, anti is provicled with an oscillatory armature 11 mounted on esteel shaft 12 which extends some distance into the'iron core of thecoil. Also mounted.

circles 50 and 51 are employed to indicate two ofmany of the ad ustmentsof the armature.

Conductor 20 continues from condenser 19 to contact 26 of the rheostat,which contact is connected with a resistance wire 27 which loops in andconnects with all of the contacts on'the rheostat, thus giving a totalof 7 8 ohms of six ohms per step, more or less as may be required.Contact 26 is connected with binding-screw 28 by conductor 29, overwhich' the current passes ,to racket 30; through bracket 30 and shortshaft 31 to binding-screw 32 to which one wire 33 of the by way-ofconductor 18 to binding-screw 43 and thence through the coil tobinding-screw 44. The current also passes from contact 16,

over conductor 17 to contact; 14. The electrode is provided with a mat 9of suitable ''absorbent material held in place by a ring 9".

Mounted on the short shafts 31 and 39,

- journaled in the brackets 30 and respeca reel upon which the cable,

"tively, and suitably insulated therefrom, is

which passes through the brass tubular handle 45 of the electrode, iswoundand unwound. The reel may be of any approved construction,preferably of a window-shade roller type, with spring for winding up thecable and pawl and ratchet stop arrangements; the cable passing throughthe tubular handle is insulated therefrom by a bushing 46.

The rheostat being on contact 16, the full current from the coil will bedischarged into the contacts 35 and 37, which are so distributed overthe insulated surface of the electrode that when the absorbent mat isplaced uponthem, the current will be evenly distributed into said mat,thoroughly charging the same, so that when the mat is pressed 1 againstthe afiected part ofthe body, the exact electrical impulse will be feltas produced by the armature movement, slow or fast (low or high)frequency, according to the adjustment of knob 24, the frequencyregulator being provided with indicating marks of 100 and 1000, andapointer 47. But when the switch-arm of the rheostata is 'moved over thecontact-points thereof toward the contact 26 the voltage at the contacts35 and 37 will be gradually reduced,

and when the switch-arm finally reaches con- It will be obvious, fromthe construction of the electrode, that only that part of the body incontact with the covered surface of the electrode, and within zone ofelectrical discharge, will be subjected to treatment, so that it ispossible to massage or treat only the afiiicted part of the body.

Having thus described my invention, what I claim is:-- 1. An electricalapparatus comprising positive and negative electrodes, a suitable sourceof electrical supply, a single field coil winding, an oscillatoryarmature supported in a closed magnetic circuit, means for regulatingthe electrical impulses-in frequency of operation, and means forregulating the intensity of the electrical impulses. 2. An electricapparatus comprising positive and negative electrodes; a suitable sourceof electrical supply, asingle, field-coil winding; an oscillatory motorin a closedmagnetic yoke, and a rheostat for regulating the intensity ofthe electrical impulses.

3. An electric apparatus comprising posi:

tive and negative electrodes; a suitable battery or other electricalsupply, a single, field-coil winding; an oscillatory motor in a closedmagnetic yoke; a current interrupter, and a voltage-switch forregulating the 1ntensity of the electrical impulses, and a frequencyswitch. for regulating the operations of impulses.

4. An electric apparatus comprising positive and negative electrodes; asuitable source of electric supply and condenser; an

induction-coil supported in a yoke of closed magnetic circuit; anoscillatory armature;

means for normally holding said armature, a

current interrupter, and a voltage and frequency regulator.

5. An electric apparatus comprising positive and negative electrodes; asuitable battery; or supply of electricity an inductioncoil supportedina yoke of closed magnetic circuit, an oscillatory armature; means fornormally holding said armature; means for regulating the movement of thearmature; a current-interrupter, a voltage-regulator, and condenser.

In testimony whereof I affix my signature in presence of two witnesses.
